If you don’t want to read it all, the title says all. I was thinking and I did small search, I didn’t find it. I found most asnwer is: What exactly you need it for?? My concern is Quality of the DI itself. Most preamp DI are the same size of a good DI Box. Why?? Should the DI box be smaller without preamp. I know Reddi is big DI box and Noble is small Preamp DI both on High price. But most DIs $100 to $300 are almost same size. I had a few of them, Listed bellow. -Sansamp Bass Driver DI - Noise -Sansamp VT bass DI ( 2 ) - Noise - MXR Bass Preamp M81 - less noise - Radial JDI - Great - Low output - Radial JDV - Great , Priced - Heavy My Current DI is: - Radial J48 - Great di for the price - Le Bass preamp DI - Really Good. I’m building a new pedalboard and I’ll do it with a DI on it already. So I was thinking about Reddi if i get the money for it or RNDI Neve. My current pedalboard has a really low noise ( Being picky on this) I’ll try to build a noise free as possible pedalboard and the next DI will be on it. Does the quality on preamp DI are less than on the DI Box??
